The Jail Division maintains all functions related to Jail and Inmate management. The jail regularly supervises over 400 inmates. All inmates are processed by deputies in Receiving, where they are fingerprinted, photographed and classified for placement in the jail.

The jail offers several programs including education, rehabilitation, mental health, ministry, and health care. Inmate work crews are employed throughout the county to help with many public works projects.

The Transport Section moves inmates to and from their court appearances, transports sentenced felons to prison, and picks up persons being held in other jails on outstanding Kalamazoo County warrants.

The Warrants Section houses and tracks the warrants for arrest out of the Kalamazoo County Sheriff's Office.
